OKLAHOMA CITY (AP) — Police in Oklahoma City discovered two semi-automatic pistols and a 12-gauge pump shotgun along with some prescription painkillers and marijuana residue on a tour bus occupied by rapper 2 Chainz and 10 other men.

The men were arrested on Aug. 22 after refusing to get off the bus following a traffic stop. The 35-year-old rapper, whose real name is Tauheed Epps, had performed with Lil Wayne and T.I. in Oklahoma City the night before.

Documents filed Tuesday in Oklahoma County District Court indicate police who searched the bus found two .40-caliber semi-automatic pistols and a partial box of ammunition for them. Twenty shells for the 12-gauge shotgun also were seized.

Police also found prescription medications hydrocodone and Flexeril but no prescriptions as well as marijuana residue.
